IMPORTANT INFORMATION
Do Not Leave the Steering Wheel Fully Turned
The combustion gases of clean diesel engines contain a large amount of water.
Therefore, if you repeatedly drive short-distances (for example: driving 8 km (5 miles)
or less for 30% of the total number of trips), the engine does not warm up sufficiently
and the water generated in the engine is not discharged. If this happens, corrosion (rust)
may occur in parts of the engine and the engine oil may deteriorate. If you repeatedly
turn off the key while the engine coolant temperature is low, such as in the case of
repeatedly driving short-distances, you should drive the vehicle for 20 km (12 miles) or
more at least once a week.

Cautions for Short Distance Driving
WARNING
• While the engine is running, if
you leave the steering wheel fully
turned for a long time or if you
repeatedly operate the steering
wheel when parking your vehicle
or when your vehicle is stopped,
the steering wheel may gradually
become hard to turn. This occurs to
prevent the power steering unit from
becoming extremely hot. This is not
a malfunction. After a while, when
the unit is cooled down, it returns
to normal. However, repeating such
steering operations may cause a
malfunction.
